Pre-Calculus Problem Solver

This book provides numerous examples that aid in understanding the complex world of precalculus.

This is the book to go to to remember how to do all those mathematical things, before calculus, we used to know but either forgot, took for granted, or shortcut and circumvented. Perfect example: solving inequalities involving absolute values -> the method I was using was producing right answers, however it was 'shotcutting' rather than solving the problem properly and robustly. Had a look inside...found an example...instant recollection and on my way again, the right way!<p>As far as I can tell there are not obvious mistakes (the review further down obviously has a really old copy or is just mistaken) and the coverage is quite comprehensive (though there are no problems for you to solve...as the title says, it is entirely solved problems and LOTS of them!). This isn't a book to teach you everything (though, I think if you worked through every example in whatever section, you would be a significantly better mathematician then when you started). As Einstein said, learng by example isn't just a way to learn...it's the only way to learn! It is a fine supplemental text and reference. The solutions are very clear, explicit and step by step. There are no logic jumps that can leave you wondering how the hell did they get from here to there? It is very systematic (even with explanations of what operation they are doing along the way- like a good teacher explaning how to do something without jumping steps). <p>Personally I regard the $18 as money well spent. It is an enormous book for the price, rich in content and extremely helpful. And given the price, what more could you want? It's a very useful addition to your library, if only as a reference work. There are basic attack strategies at the beginning of each chapter and masses of problems! Sure, the theory it covers is contained within the problems, not explicitly...hence you may need your course book along with this (or maybe as I said earlier: just try to learn from this book, which might be kinda weird and fun).<p>In all: well worth 5 stars! YOu can't expect a magical panacea for all your mathematical woes to be found within...but it tries! And it does deliver a great deal...<p>Happy Mathematics!
